Could you purchase Turner Classic Movies- greatest classic films collection-Marx Brothers and if you purchase please place a hold for me?
The collection management dept. doesn't usually buy older DVDs--harder for them to get from their usual suppliers. I did find a more newly released Marx Brothers set which includes some of the films on the set you requested, so I've taken the liberty of requesting that the library buy that one. You should see notification in your account (on the Suggested Purchases page) if they buy it.
Hope this helps!
